Granted: 2006-02-07
Abstract: A high-load slip system allows better transmission of loads from the slips (32) to the body (30). The cone (36) comprises longitudinal slots (42) and the body comprises tabs (46) which are disposed in those slots.  The load is transferred from the slips to the cone and into the tabs which reside in the slots. The arrangement can be configured to share the load between the tabs extending from the body and the actual body itself after a small amount of collapse on the cone, leaving the body to support the cone, both through the tabs and on the outside diameter.

Abstract: A stabilizing assembly includes a fastener. The head of the fastener includes a center, a first radial surface and a second radial surface. The first radial surface defines a first radius from the center. The second radial surface defines a second radius from the center. The first radius is greater than the second radius. The assembly includes a coupling element having a rod receiving opening for receiving a stabilizing rod, a bore for receiving the fastener, and a conical-shaped seat for engaging the first radial surface when the fastener is positioned in the bore. A locking element applies a force upon the stabilizing rod. The rod in turn, engages the second radial surface for forcing the underside of the head against the conical-shaped seat so as to prevent further pivotal and rotational movement of the fastener and the coupling element relative to one another.

Abstract: Provided is a cationized silica dispersion prepared by dispersing dry processed silica and a cationic resin in a polar solvent, wherein a concentration of dissolved silicic acid at 25°C is 200 ppm or less. This cationized silica dispersion does not substantially form coagulated matters when blended with a binder and therefore can advantageously be used for producing a coating composition such as a coating composition for forming a gas barrier layer, a corrosion preventive coating composition and a coating composition for ink jet recording paper.

Title: Outil de tige de pompage pour canalisations de chauffage a eau
Inventor: NEWMAN FREDERIC M
IPC: E21B19/16
Filed: 2002-04-12
Granted: 2007-01-02
Abstract: Des pinces pour assembler des tiges de pompage pour canalisations de puits de pétrole comprennent un commutateur qui capte le mouvement de la clé de retenue de la pince par rapport au logement de la pince. Lors du vissage des deux tiges de pompage dans un accouplement fileté, une mâchoire supérieure des pinces fait pivoter la tige de pompage supérieure par rapport à la tige de pompage inférieure, pendant que la clé de retenue maintient la tige de pompage inférieure relativement stationnaire. Lorsque les pinces appliquent un couple qui indique que la connexion filetée dépasse le serrage à la main (p.ex., à l'épaulement), une force de réaction au couple ramène la clé de retenue à une position qui enclenche le commutateur. Une commande réagissant au commutateur et au capteur de rotation surveille et contrôle le déplacement périphérique de la connexion filetée au-delà de l'épaulement. En captant directement la position de la clé de retenue, le commutateur peut identifier de façon cohérente l'épaulement indépendamment de la pression hydraulique de la pince, ce qui permet d'éviter les erreurs liées à la viscosité de l'huile.

Abstract: A communications system includes a plurality of recipient processors located at remote locations with respect to each other and connected to an information provider processor (12) over a communication network. The provider (12) and recipient (124) processors may communicate through the Internet (18). The provider processor (12) can provide information from any suitable source over a communication network. However, access to the information by the recipient processors is controlled based on the geographic location or region of the recipient processors (124). Each recipient processor is operably associated with a positioning system, such as a global positioning system GPS (130, 126) to provide its location. The location information is used to determine whether or not the processor requesting the information is within a restricted or non-restricted region. This determination may be made by comparing the geographic information of the recipient processor with a list of non-restricted or restricted geographic locations or regions.

Granted: 2007-01-30
Abstract: A transcoder architecture that provides the lowest possible complexity with a small error, e.g., for converting an MPEG-2 bitstream into an MPEG-4 bitstream. The transcoder reads header information (304) from an input bitstream and provides a corresponding header in the new format for the outp ut bitstream. In one embodiment (Fig. 3), a low complexity front-to-back transcoder (with B frames disabled) avoids the need for motion compensation processing. In another embodiment (Fig. 4), a transcoder architecture that minimizes drift error (with B frames enabled) is provided. In another embodiment (Fig. 5), a size transcoder (with B frames enabled) is provided, e.g., to convert a bitstream of ITU-R 601 interlaced video coding with MPEG- 2 MP@ ML into a simple profile MPEG-4 bitstream which contains SIF progressive video suitable for a streaming video application. For spatial downscaling of field-mode DCT blocks, vertical and horizontal downscalling tehniques are combined to use sparse matrixes to reduce computations.
